The Los Angeles Times reported on Saturday that dozens of voters have complained they were duped by a firm working for the GOP into switching their party registration to Republican while being told they were signing a petition for tougher penalties on child molesters.
The switches could impede Democratic get-out-the-vote efforts and could prevent those affected from voting in next year's Democratic primaries. Some of the voters were even switched to absentee status, meaning they could lose their vote entirely if they show up at the polls on Election Day without bringing an absentee ballot.
This seems to me to be a much worse transgression than anything the right tries to drum up regarding ACORN. If you're interested, here is the LA Times story.
